1. A screw tower for use in medical procedures comprising:
a first end;
a second end;
a main body separating said first end and said second end by a length, said main body comprising a first elongated member and a second elongated member, said first elongated member and said second elongated member separated by a space and connecting at said first end by a first end surface, said space defining an interior region;
a first surgical screw engagement member configured to removably engage with an outer surface of a first side of a surgical screw tulip, said first surgical screw engagement member comprising an exterior surface, an interior surface having a curvature shaped to mirror a curvature of said surgical screw tulip it engages with, and a first surgical screw locking member, said first surgical screw locking member comprising a first wall, a second opposing wall, a closed end, and an open end defined by a space separating said first wall and said second wall, said first wall, said second wall, and said closed end are arranged to define a first surgical screw locking member interior, said first surgical screw locking member interior sized and shaped to receive and secure to a conjugate or keyed shaped tower engagement member positioned on said outer surface of said first side of said surgical screw tulip; and
a second surgical screw engagement member configured to removably engage with an outer surface of a second side of said surgical screw tulip, said second surgical screw engagement member comprising an exterior surface, an interior surface having a curvature shaped to mirror a curvature of said surgical screw tulip it engages with, and a second surgical screw locking member, said second surgical screw locking member comprising a first wall, a second opposing wall, a closed end, and an open end defined by a space separating said first wall and said second wall, said first wall, said second opposing wall, and said closed end are arranged to define a second surgical screw locking member interior, said second surgical screw locking member interior sized and shaped to receive and secure to a conjugate or keyed shaped tower engagement member positioned on said outer surface of said second side of said surgical screw tulip,
wherein, when engaging with said surgical screw tulip, rotation of said main body in one direction causes said first surgical screw locking member to engage with said tower engagement member positioned on said first side of said surgical screw tulip simultaneously as said second surgical screw locking member engages with said tower engagement member positioned on said second side of said surgical screw tulip, and rotation of said main body in an opposite direction causes said first surgical screw locking member to disengage with said tower engagement member positioned on said first side of said surgical screw tulip simultaneously as said second surgical screw locking member disengages with said tower engagement member positioned on said second side of said surgical screw tulip.
